How to include all the invoices in the last payment run

Hello All,

In one of our existing Co Cds, We are executing last payment run and clear all the vendor liabilities. I can see total opens 140. But when I am executing APP, It has picked up only 35. We would like to pay Vendors irrespective of due dates. Pls let me know how to include all the invoices in the last payment run.

Pls let me know what settings I should maintain APP. I can see last invoice date is 08/21/2013. Hence, I have given next payment run date as 08/31/2013.

Still it has picked up only 35 invoices.

Thanks
